  • question_answer Which of the following reaction is not feasible [CBSE PMT PMT 2002]

    A) \[2KI+B{{r}_{2}}\to 2KBr+{{I}_{2}}\]

    B) \[2{{H}_{2}}O+2{{F}_{2}}\to 2HF+{{O}_{2}}\]

    C) \[2KBr+{{I}_{2}}\to 2KI+B{{r}_{2}}\]

    D) \[2KBr+C{{l}_{2}}\to 2KCl+B{{r}_{2}}\]

    Correct Answer: C

    Solution :

    \[2KBr+{{I}_{2}}\to 2KI+B{{r}_{2}}\] Iodine is a less electronegative compare to Bromine hence iodine does not change \[B{{r}^{-}}\]to \[B{{r}_{2}}\].
